Abstract

Implant overdentures are widely used as a treatment method to restore oral function in completely edentulous or partially edentulous patients with severe bone resorption. Using a milled bar, it is mechanically advantageous as the implant fixtures are splinted. Applying additional attachments to the bar has the advantage of dispersing the stress applied to the implant. In this case, a patient who used implant overdentures using 4 implants wanted to fabricate a new prosthesis due to repeated fractures of the denture and weakened retention. Milled bar with ADDTOC attachment and zirconia prosthesis were fabricated by CAD-CAM method and mechanically and aesthetically satisfactory results were obtained.
